Direct Inward System Access (DISA) Single Line Digital Telephone Features

Direct Inward System Access (DISA)

Outside callers with telephones that send Dual-tone Multi-frequency (DTMF) tones (push-button dialling) can call in on Exchange lines programmed for DISA and dial stations or outgoing Exchange lines without going through an attendant or operator.

1.From outside the system, call the DISA Exchange line phone number:___-______.

See the System Administrator for this number.

2.Listen for the repetitive ringback tone signal, followed by dial tone.

Try again if you hear busy tone.

3.During the 10 secs. of dial tone, make your call.

4.If you hear busy tone, press *.

5.When you hear dial tone, call again.

If a number is not dialled, the system automatically causes the DISA Exchange line to ring at telephones as a normal incoming call. Then, if the call is not answered within 15 seconds after the ringing starts it disconnects.

To call another station after completing a DISA station call, the internal party must transfer you. Station Paging and System Paging cannot be made on DISA calls.

If the call is not answered after 6 rings or 24 seconds, whichever occurs first, you hear busy tone.
